ROBA®-slip hub the load-holding, frictionally-locking safety clutch ROBA® is a trade name which has been the symbol of quality and experience in clutch construction for decades. A comprehensive range of torque limiters has originated from the robust jaw clutch (ROBA®-safety slip clutch). ROBA®-slip hub devices are simple to use. The torque table makes it possible to set the torque according to a scale and offers considerably simplified installation. ROBA®-slip hub devices are reasonably-priced drive elements which protect machinery and equipment against costly damage, and against downtimes resulting from time-consuming repairs. As a result of their high-strength materials and careful manufacture with optimum utilisation of space, ROBA®-slip hub devices are smaller than similar clutches on the market. Twelve different designs and combinations are available. We have a solution for all drive units. However, if any of your wishes remain unanswered, please contact us.

ROBA® stands for: trust in safety.

Application ROBA®-slip hub devices are used as overload protection for machine drives with chain sprockets, toothed wheels or pulleys. The ROBA®- slip hub is used wherever expensive and sensitive motors, gearboxes or machinery components need to be protected against overloads. If overload occurs, the drive element slips and, therefore, limits the torque. ROBA®-slip hub devices are used in packing machines, transport systems and equipment, construction machinery, textile machinery, agricultural machinery, mechanical handling equipment, feed units, loading systems, in equipment for the chemical industry and in machinery and equipment in general industrial engineering.

Design Despite their simple construction, ROBA®-slip hub devices are high-quality machine components. The ROBA®-slip hub is fully machined and phosphated and, therefore, protected against rust. It is a fully enclosed construction, so that dirt is prevented from reaching internal components. The ROBA®-slip hub, which is a rotating component, fits very easily into all drive systems as a result of its smooth construction. It is particularly suitable for attachment to the outside of machines and for those systems which must be kept clean easily, e.g. in the food industry. ROBA®-slip hub devices are designed in such a way that they can be adapted very easily to the most varied of working conditions, e.g. high slipping frequency and low torque or low friction work and extremely high torque, as well as all intermediate stages of torque and friction work, and the desired lifetime.

ROBA® – a Well-known Trade Name

The set screw applies pressure onto the keyway of the shaft, preventing axial movement of the slip hub.

Fig. 1 Type 100.110

The short, robust hub ensures compact overall dimensions for the complete slip hub, together with easy assembly and fitting.

Four wide claws engage in the keyways

of the hub and guarantee reliable torque transmission

even under impact loads or reversing load conditions.

Asbestos-free friction linings with a large surface area and a low wear rate ensure a long lifetime.

Adjusting nut together with a graduation scale

for simple torque adjustment and wear re-adjustment

Positive-locking torque adjustment securement via the lock washer

and the locking screw to prevent the adjusting nut

loosening

Cup springs with low characteristic curve

keep torque reduction due to wear low. Alternative

spring layerings ensure a wide torque range per size.

The bearing bushing width can be shortened to suit the width of the drive element.

A speed monitor (available on request) prevents excessively long drive element slippage or serves on the output to monitor the chain drive against breakage.

Technical Explanations 19

Torque Adjustment 21

Installation Examples 22

FunctionThe drive element (12) (chain sprocket or V-belt disk) is placed on the bushing (7) as shown in Figure 2 and clamped between the friction linings (6) with the aid of the thrust washer (2), the cup springs (5) and the adjusting nut (3) with the lock washer (13). The more powerfully the cup springs (5) are compressed by the adjusting nut (3), the higher the torque at which the drive element (12) slips. The precise torque adjustment operation is described on page 21.

It should also be noted that the difference in torque after friction lining wear is lowest with single cup spring layering and highest with triple cup spring layering. In addition, a torque adjustment in the uppermost quarter of the maximum torques gives a particularly even adjustment (the spring characteristic curve has its smallest increase in this area). Other friction linings are also available for special applications (see further details on page 19).The ROBA®-slip hub is available for three different torque ranges.

Rule of thumb:

ROBA®-slip hub for high friction work and low torque (single-layer cup springs, single contact force).

ROBA®-slip hub for medium friction work and higher torque (double-layer cup springs, double contact force).

ROBA®-slip hub for low friction work and very high torque (triple-layer cup springs, triple contact force).

Please observe the operating speed or slipping speed (see Explanation on page 19)! 3

ROBA®-slip hub with rustproof friction lining Type 100._2_Sizes 01 to 6

Used in conjunction with cast iron and steel surfaces, the friction linings can form a rust compound which increases the friction value and therefore the torque considerably. However, a high increase in torque makes the machine unsafe.

For this reason, ROBA®-slip hubs can be equipped with disks made of stainless steel, which do not stick to the friction lining and do not form rust compounds.

ROBA®-slip hubs with rustproof friction linings offer higher security on drives operating in open air conditions, in particularly wet conditions or those which are subject to long downtimes.

On design M (Type 1000), the drive element is clamped spring- pretensioned between two friction linings.

The optimised performance capability of the clutch design L (Type 1010) is achieved via a second pair of friction linings. Knobs are provided in the transmission flange for torque transmission onto the drive element. These knobs grip via positive locking into the bores in the drive element (drive element not included in delivery).

ROBA®-clamp devices are used to provide overload protection in machine drives with shaft ends without a keyway.

The frictionally-locking, backlash-free clamping hub is attached to the shaft by tightening one single screw. This means that axial attachment using a shaft collar, adjusting screws or a press cover are unnecessary.

The ROBA®-clamp is used in packing machines, transport machines and devices, construction machinery, textile machinery, agricultural machinery, conveyor systems, feed devices, loading systems, in chemical industry machines as well as in devices and systems for general mechanical engineering.

ROBA®-min Types 121._ _ _ and 123._ _ _Sizes 1 to 5

ROBA®-min Types 121 and 123 are slip hubs for drive elements, chain sprockets or toothed wheels with especially small diameters. ROBA®-min devices are used in particular for high transmission ratios or also for double or triple-row chain sprockets or wide toothed wheels.

When compared with the standard Type 100, the ROBA®-min Types 121 and 123 transmit lower torques.

An advantage of Types 121 and 123 is that the drive element comes very close to the shaft bearing as a result of the short hub collar.

Type 170._ _ _Sizes 0 to 5

ROBA®-slip hubs are used to provide overload protection in machine drives with chain sprockets, V-belt pulleys or toothed wheels. Type 170 has a longer hub than the standard Type 100. As a result, Type 170 is particularly suitable for wide drive elements. The permitted limit torques and the diameter correspond to the standard model. ROBA®-max Type 170 can transmit a higher torque than a ROBA®-min Type 123 with the same installation width.

Type 170 can be used for all mechanical engineering applications.

Type 160._ _ _Sizes 1 to 5

ROBA®-slip hubs are used to provide overload protection in machine drives with chain sprockets, V-belt disks or toothed wheels. The difference between Type 160 and the standard Type 100 is that the former has a needle bearing instead of a bearing bushing. As a result, Type 160 is particularly suitable for applications with high radial loads, high slipping frequencies and increased shaft run-out accuracy (toothed wheels).The drive element is pressed onto the needle bearing as shown in Fig. 16. Please ensure that the right-hand side of the needle bearing is flush with the right-hand side of the friction lining. The needle bearing with the drive element and the two friction linings are then pushed onto the hub. Type 160 can be used throughout the mechanical engineering industry.

Torques – Cup Spring Layering

The cup spring layering in Figs. 22 – 24 show our ROBA®-slip hub standard design. Each layering results in a different spring characteristic curve or spring force (torque). A rule of thumb when using ROBA®-slip hubs is:

ROBA®-slip hub for high friction work and low torque; single-layer cup spring.

ROBA®-slip hub for medium friction work and larger torques; double-layer cup springs.

ROBA®-slip hub for low friction work and very high torques; triple-layer cup springs.

Speeds

The ROBA®-slip hub is thermically loaded depending on the slipping speed, slip time and the set torque. To make sure that the ROBA®-slip hub friction linings are not overheated or destroyed, the specified friction parameters must not be exceeded. The recommended values in the Reference Values Diagram (Diagram 1) show the maximum slipping speed limits of the standard friction linings in dry running. These speed limits refer to a maximum slip time of 1 second. For longer slip times, the slipping speed must be reduced. If in doubt, please carry out the friction work calculations for the respective application.

If the permitted slipping duration is exceeded, the ROBA®-slip hub will be overloaded.=> Destruction of the friction linings

A speed monitor prevents the drive elements slipping for an excessively long time. Please ask the manufacturers for devices adapted to your application.

The torques stated in the Table “Technical Data” refer to drive elements made of steel or cast iron!

During the start-up phase (matching the friction surfaces), after long downtimes and during or after long slipping occurrences, the friction lining wear pattern and the friction coefficiencies may change. This can lead to changes in torque.

Friction Linings

As shown in Table 1 below, four different friction linings are available. The torque and the speed values in the slip hub catalogue are applicable for the standard friction lining during dry running. For other friction linings, please find the correct values in Table 1 or ask the manufacturers for special application values.

Fig. 25 Fig. 26

The torque behaviour of the ROBA®-slip hub on friction lining wear is clearly shown in Figs. 25 and 26. With single cup spring layering, the torque reduction on wear is very low (Fig. 25). With double cup spring layering, the change in torque is larger (Fig. 26), and with triple cup spring layering, the torque reduction is highest. However, the cup springs are designed with a relatively flat characteristic curve so that large wear paths can occur without larger drops in torque.

For special applications, weaker cup springs are available for the individual slip hub sizes, with which the minimum torques can be under-run. Other cup spring layerings can be produced (e.g. combinations of double and single-layering) individually for special applications. In Figs. 25 and 26 it is shown that a torque adjustment in the uppermost quarter of the spring characteristic curve (torque) produces a particularly even torque, as the spring characteristic curve has its smallest increase in this area.

Technical Explanations Bearing Bushing

If the drive element installation width is not specified on order, we deliver the bearing bushing (Fig. 33) for the maximum installation width (bmax). If a smaller installation width is required, the bearing bushing must be shortened accordingly on the end without the inner chamfer, see the Example below. The bearing bushing is to be installed with the inner chamfer facing forwards, see Fig. 33.

Fig. 27Adjusting Nut 0Sizes 0 – 5

Adjusting Nuts

Fig. 31

The standard adjusting nut for Sizes 0 – 5 (adjusting nut 0, Fig. 27) is adjusted using a face wrench (Fig. 31). The adjusting nut is secured using a lock washer with four projections as well as a hexagon head screw which is screwed through the adjusting nut into the lock washer bores.

The standard adjusting nut for Sizes 6 – 12 (adjusting nut 0, Fig. 28) has no lock washer. It is secured against twisting with a radial set screw.

Additionally, we provide an adjusting nut for radial adjustment for Sizes 0 – 5. Adjustment takes place here using a hook wrench (Fig. 32). On this design (adjusting nut 1, Fig. 29), the thrust washer must be shortened. The device is additionally secured against twisting using a radial screw-in set screw, which is pressed into one of the four hub keyways.

For triple-layering on the ROBA®-slip hub Sizes 0 – 2, the adjusting nut 0 or 1 is used. On Sizes 3 – 5, the adjusting nut 2 is used (Fig. 30).The adjusting nut 2 for the ROBA®-slip hub varies from the adjusting nut 0 or 1 for the ROBA®-slip hub as it has six axial set screws for torque adjustment. As with adjusting nut 1, it is secured using a radial set screw.For high torque adjustments, it may be necessary to lengthen the leveron the face wrench or hook wrench (e.g. extension using a pipe).

* The total length of the clutch is not affected.

Maintenance – Installation

Due to its smooth construction, the ROBA®-slip hub is easy to clean. As the friction linings wear down, the ROBA®-slip hub must be re- adjusted or, if they are very worn, the friction linings must be replaced. Apart from this, the ROBA®-slip hub needs no maintenance. During installation, please ensure that no grease or oil comes into contact with the friction surfaces. In the area of the friction surfaces, the drive element surface must be finely polished and have exactly plane parallel surfaces (see Fig. 34 and Table 3).

Torque Adjustment

On the ROBA®-slip hub devices Sizes 1 – 5, the rear side of the thrust washer (Item 2) is engraved with 12 markings (24 markings on Size 0), and the adjusting nut (Item 3) is engraved with four markings (see Fig. 35). The adjusting nut with locking washer is adjusted by hand up to the contact on the cup springs. The four notches on the adjusting nut and the notches on the thrust washer must align. Then the adjusting nut should be turned by the number of graduation lines which equal the required torque.

An Adjustment Table (Fig. 37) is adhered to the clutch, from which the number of graduation lines necessary for the required torque can be read off. If a required torque value lies between two graduation lines, please adjust to the smaller value (positive spring force tolerance). After the torque adjustment has been made, please secure the adjusting nut by turning the locking screw (Item 4).

The ROBA®-slip hub with triple cup spring layering has no Adjustment Table adhered to it. Torque adjustment is carried out in the following way: Please tighten the adjusting nut without using a lot of force. Then adjust the individual screws in the adjusting nut evenly in approx. 1/4 turns to the specified dimensions “b” or “a” shown in the Adjustment Diagram (if necessary, please order the Table from the manufacturers). In this way the required torque is obtained.

For initial adjustment, the ROBA®-slip hub should slip several times at 50 % of the torque specified in the Catalogue, in order to achieve a clean wear pattern on the friction lining.

Depending on the slipping frequency, occasional re-adjustment is necessary due to friction lining wear.

The ROBA®-slip hub can of course be delivered complete with a drive element at extra cost, pre-adjusted to the set torque.

Axial attachment onto the shaft is carried out via a press cover and a screw, screwed into the central thread of the shaft. Slip monitoring is carried out by a speed monitor (available on request) with an external initiator.

ROBA®-slip hub with rustproof friction lining

Type 100.220

Features

Slip hub with disks made of stainless steel to prevent the friction linings rusting.

Application

Overload protection for machines operating in open air conditions, in particularly wet conditions or machines subject to long down-times.

Technical Details

The slip hub is held on the shaft via a set screw which applies pressure onto the keyway. The rustproof disks do not adhere to the friction lining and do not form rust compounds. A speed monitor (available on request) prevents excessively long slippage on overload.

ROBA®-slip hub with needle bearing

Type 160.210

Features

Needle bearing in place of the standard bearing bushing; suitable for continuous slipping at low speeds and torques.

Application

Drives with high radial loads, high slipping frequency and increased shaft run-out accuracy.

Technical Details

Axial attachment onto the shaft is carried out via a set screw and a press cover, or, as indicated in the drawing, via a locking ring.

The width of the drive element is not variable due to the fixed needle bearing length.

ROBA®-min

Type 121.210

Features

Slip hub with a standard friction lining and a small bronze friction lining on the hub collar side.

Application

For drive elements with very small outer diameters and large installation widths.

Technical Details

The hub collar and a friction lining are significantly reduced.

On the side with the standard friction lining, an intermediate flange is additionally attached between lining and drive element and pinned to the drive element.

Installation ExamplesROBA®-max

Type 170.110

Features

Slip hub with a long hub, the transmittable torques correspond to the standard ROBA®-slip hub.

Application

For very wide drive elements, e.g. multiple-row-chain sprockets.

Technical Details

The ROBA®-max can take drive elements with a large width range. The bearing bushing is modified to the required installation width. Attachment onto the shaft is carried out via a set screw which applies pressure onto the keyway.

ROBA®-lastic

Type 131.110

Features

Slip hub for connection of two shafts with polygon-shaped, highly flexible rubber elements.

Application

Overload protection, connection of two shafts in drives with large shaft misalignments, impacts and torsional vibrations.

Technical Details

The slip hub is attached onto the shaft using a press cover. The flexible coupling hub sits without attachment frictionally-locked on the shaft. Torque transmission takes place via a rubber element which has a high misalignment compensation capability and damps torsional vibrations and impacts.

ROBA®-LD - torsionally rigid

Type 134.110

Features

Slip hub combined with a torsionally rigid flexible all-steel coupling (ROBA®-D coupling).

Application

Overload protection, connection of two shafts and shaft misalignment compensation with low torsional backlash torque transmission.

Technical Details

The slip hub is attached using a press cover. The ROBA®-D hub is attached using a set screw onto the shaft. The ROBA®-D coupling transmits the torque backlash-free. Low torsional backlash results from the thrust washer jaw backlash in the slip hub outer keyways.
